Abstract:
      The CNT bundles can be jagged and used as template to load the precursor H2WO4. The H2WO4 seeds can be enclosed by the jagged CNT template during liquid precipitation process. The H2WO4clusters with avarage size of 500Snm are consisted of nanosized H2WO4with 10-20 nm diameter, which display high specific surface area of 85.24 m2 g-1 and total pore volume of 0.2933 m3 g-1. After thermal treatment of H2WO4/CNTs at oxygen atmosphere, nano-WO3 particles attached to sphere-like micro-WO3 can be easily obtained by removing the CNT template. Its specific surface area and total pore volume is 18.7 m2 g-1 and 0.2055 m3 g-1respectively. These results indicate that the jagged CNTs can play an important role for effective mediation of WO3 with hierarchical size, and exhibit excellent prospects for preparation of micro-nanostructured materials.
